AXIS P3346-V Fixed Dome Network Camera
Video and Audio
Day/Night
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at night, or when using an external IR lamp, set the IR cut filter to Off. This increases light sensitivity and allows the product to “see” infrared light. The image is shown in black and white when the IR cut filter is off.
If using automatic Exposure control, set the IR cut filter to Auto to automatically switch between On and Off according to the lighting conditions.
The camera lens is IR corrected, which means that it maintains focus in mixed light, however a small focus adjustment is recommended when IR illumination is used. Select Enable focus adjustment for IR illumination to automatically adjust the focus when the IR cut filter switches between on and off.
View Area
A view area is a cropped part of the full view. Each view area is treated as a video source in Live View and has its own video stream and PTZ settings.
When setting up a view area it is recommended that the video stream resolution is the same size as or smaller than the view area size. Setting the video stream resolution larger than the view area size implies digitally scaled up video after sensor capture, requiring more bandwidth without adding image information.
To enable, go to Video & Audio > Camera Settings and select Enable View Areas.
To add a new view area:
1.Go to Video & Audio > View Area.
2.Click Add.
3.The new view area appears under Selected view area. Enter a descriptive name in the Name field.

7.Click Save to save the settings.
To modify a view area, select the view area in the list and modify the settings as required. Click Save.

Note
The PTZ functionality is useful during installation of the Axis product. Use a view area to crop out a specific part of the full view.
Overlay
Overlays are used to provide extra information, for example for forensic video analysis or during product installation and configuration. Overlays are superimposed over the video stream.
An overlay text can display the current date and time, or a text string. When using a text string, modifiers can be used to display information such as the current bit rate or the current frame rate. For information about available modifiers, see File Naming &
Date/Time Formats in the online help 
.
It is also possible to display text when an action rule is triggered, see .
To enable overlays:
1. Go to Video & Audio > Video Stream and select the Image tab.
